profanity-v1.3

This release mainly improves performance on nVidia cards by improving the Keccak implementation that apparently was a major bottleneck on my GTX 1070. I saw a speed boost of about 4x and it's now outperforming all of my RX 480/580 cards.

Some other minor changes by me and other people since the last release is included in this binary:

• Possible to search for contract addresses
• Infinite wait on initialization step fixed
• Output improved by writing to stderr and also by clearing current line when outputting new result
• Max score of 40 is now possible
• Mask now actually possible in mode --matching as given in example in --help
